Youtube Trick - Advancing the video to a specific playback point

If you ever wanted to link to a video in YouTube that was lengthy, but had a very interesting part partway through, there is a hack to allow you to begin playback at a precise time. You can specify the minutes and seconds of the start time like this:

add #t=53s to the end of the URL to start at 53 seconds into it:

CODE
http://www.youtube.com/watch?v=MBGeNeofk0A#t=53s

add #t=1m57s to the end of the video URL to start playback at 1 minute 57 seconds:

CODE
http://www.youtube.com/watch?v=MBGeNeofk0A#t=1m57s

Think of this as bookmarking your video clips! Now you can link to a video, and have an index of the segments included, which link right to that precise moment
